Description
Technical field
The present invention relates to a kind of gel skeleton type slow releasing tablet of Chinese medicine Cutis Bufonis, specifically the preparation of Cutis Bufonis extract gel skeleton type slow releasing tablet and in the application of clinicing aspect.
Background technology
Bufo siccus (toad) also cries Oviductus Ranae.Amphibian, body surface have many pimples, in poison gland is arranged, be commonly called as toad, leprosy thorn.Being divided into two kinds of Bufo siccus and Bufo melanostictus in China, is a kind of tcm clinical practice medicinal former animal commonly used.Just on the books in the Ancient books such as Shennong's Herbal, " China's book on Chinese herbal medicine ", " Mingyi Bielu ".Bufo siccus " acrid in the mouth, cool in nature, poisonous.GUIXIN, liver, spleen, lung meridian ", can " detoxicating and resolving stagnation of pathogens, removing food stagnancy diuretic, destroying parasites for curing malnutrition.Cure mainly carbuncle, furuncle, carbuncle on the back, scrofula, the malignant boil ， mass in the abdomen hypochondriac lump, tympanites, edema, infantile malnutrition, tetanus, chronic cough and asthma ".The Chinese crude drug dry maxima skin is to remove the Bufo siccus of drying or drying behind the internal organs, and the structures such as bone, muscle are arranged.And Cutis Bufonis is after Bufonidae animal Bufo siccus Bufo bufo gargarizans Cantor or Bufo melanostictus Bufo melanostictus Schneider are taked Venenum Bufonis, the execution of choping off the head catches neck shoulder place skin to pull backward the bag-shaped skin with extremity that stripping obtains.Skin depth 0.2～0.3mm only is shrinkage Gou contraction shape after drying or drying, and extremity stretch or distortion, outer surface smoother, and inner surface has numerous miliaria scrofulas not of uniform size.Quality is firmly and extremely tough and tensile, and the dermatomere shape is difficult for bending, and difficulty fractures.Section is smooth, and fracture has fiber to link to each other.Sun Simiao claims: " it is swollen except disliking that toad is sloughed off (clothing), and god also." the Li Shizhen (1518-1593 A.D.) Compendium of Material Medica claims: " the toad clothing is that it holds sufficient the essence of five ZANG-organs and six FU-organs gas, receives the China of world negative and positive precious, if one of obtain, all foul diseases do not have and do not heal.”
The method of extracting at present effective ingredient in the Cutis Bufonis roughly has two kinds: a kind of is the method that adopts water extract-alcohol precipitation, and water soluble ingredient is more in the products therefrom, contains the bufogenin constituents of trace.Relevant report has: " cinobufacin (Cutis Bufonis) extract production process " (number of patent application 200510005277.4) is the preparation method of extract in the HUACHANSU ZHUSHEYE of Anhui Jinchan Biochemical Co., Ltd. development, oral liquid, the tablet.Another kind is to adopt organic solvent extraction, and extract separates through chromatographic column, organic solvent gradient elution in varing proportions.Relevant report has: " preparation of three kinds of anticancer compounds and preparation method thereof in Bufo siccus or the Venenum Bufonis " (number of patent application 200610045893.7), the total content of resibufogenin, cinobufacin and three kinds of compositions of Toadpoison Medicine 〉=80% in the extraction product; " a kind of Venenum Bufonis extract and preparation method thereof " (number of patent application 200710041880.7), the percentage by weight of the above-mentioned three kinds of products of gained 〉=90%; " toad skin total alkaloid and preparation thereof and analytical method with and preparation " (number of patent application 200710020339.8), wherein the indoles total alkaloid content is 50%～95%, the total amount of cinobufagin and resibufogenin is 0.02～0.08%, and the peaceful content of Bufo siccus thiophene is 20%～50%.Fat-soluble active constituent content is higher in this kind method extract, but complex process, complex operation, and cost is higher; By contrast, the first method simple possible, cost is low, and the content of effective ingredient is enough to meet clinical needs in the extraction product, easily promotes and adopts.
Modern pharmacology studies show that Cutis Bufonis extract has the effects such as heart tonifying, antitumor, local anaesthesia, analgesia, antiinflammatory.Be usually used in clinically in the treatment, the diseases such as late tumor and chronic hepatitis B.Common formulations has conventional tablet, oral liquid, capsule and injection etc. at present.But all there is drawback to a certain degree in these dosage forms, take medicine 3～4 times each 3～4 every day such as conventional tablet, medicining times is many, and dosage is large, and tumor and chronic hepatitis B patient all need this medicine of long-term taking, there is very large inconvenience, causes patient's medication poor compliance.Therefore, be necessary to study a kind of novel form, improve to a certain extent the deficiency that existing dosage form exists.
Oral sustained-release preparation can reduce medicining times because of it, reduces blood concentration fluctuation, and medicament curative effect enhancement reduces the focus of paying close attention to for people that forms of untoward reaction.Matrix tablet is because of its low production cost, and technique is simple, becomes one of the most frequently used oral sustained-release preparation.Hydrogel matrix tablet is a kind of in the matrix sustained release tablet, and the production development cycle is short, easily drops into suitability for industrialized production, has very strong practicality, occupies 60～70% of listing matrix tablet.Hydrogel matrix tablet (Hydrophilic Matrix Tablet) is the tablet of making as framework material take hydrophilic polymer or natural gum class.Can meet by framework material the gel barrier control drug release of water or Digestive system formation.
Because method of granulating commonly used is with mixing of materials all in the sustained-release tablet recipe at present, add an amount of wetting agent or binding agent and granulate, the Chinese medicine sustained release tablets of preparation drug release rate in early stage is slower like this, later stage release quantity not sufficient.In use produce effects is slow, wants to obtain effectively to treat concentration and takes longlyer, can not reach the requirement of desirable slow releasing preparation.
Existing studies show that can be improved the rate of release of slow releasing preparation Chinese medicine by adding porogen, increase total release percentage.Principle is that porogen is met water or Digestive system dissolves, in the gel layer barrier, form complicated duct, destroyed the seriality of gel, make water or Digestive system can penetrate in the matrix tablet, accelerate dissolving and the diffusion of medicine, improve aquation and the corrosion speed of framework material.Generally, porogen is less on the release impact in medicine early stage, and is larger on later stage release impact.Reason is, in the starting stage of drug release, discharges mainly take concentration difference as motive force; And when drug release to a certain extent, the inside and outside concentration difference of medicine hour, the principal element that affect release is then changed into the framing structure of medicine itself by concentration difference, namely the release duct how much.At this moment, the effect of porogen manifests, and slow releasing preparation later stage burst size increases.The slow releasing preparation release that obtains desirable.
